In Reply to: I need help with voltage problem?Can someone here please help me out? posted by Brian McGowan on March 24, 2007 at 17:48:07:
Most likely you will see a small DC motor and speed regulator circuit on a PC board. Sometimes input voltage and polarity are indicated on the PC board, which should help you. If there are no markings, track connections to electrolytic capacitor across the input, which will give you polarity. Voltage should be 30-50% lower than capacitor rating. I would use 3 V first (2 batteries) and test how it works. If it does not, I would increase voltage little by little to the point at which speed is stably maintained.
